Abstract

The US version of the BMW 325i is the first BMW to meet the world’s strictest emissions limit, the SULEV (Super Ultra Low Emission Vehicle) standard. A central feature of the exhaust system, which was developed by Boysen as a full system partner of BMW, is the use of ultrathinwall substrates from NGK.
